According to the present invention, the pixel resolution of the input image is adjusted by oversampling an analog signal representative of the input image at a higher frequency than the pixel rate of the original image, then digitally downscaling to the desired horizontal resolution of an output image. The horizontally downscaled image is then stored in a buffer memory and subsequently scaled up to the desired vertical resolution of the output image. Preferably, oversampling of the analog signal is performed at a frequency that is an integer multiple of the input pixel rate, thus providing coherent sampling to help avoid aliasing artifacts in the sampled image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for increasing pixel resolution of image using coherent sampling","description":"An apparatus and method for adjusting the pixel resolution of an input image is disclosed.
